Abstract
A compliant device for a scroll-type fluid compressor including a drive shaft having an axis of rotation. A disk shaped rotor is affixed at one end of the drive shaft and includes a drive pin extending from the side of the rotor opposite the drive shaft. The drive pin 13 disposed at a location eccentric to the axis of rotation of the drive shaft and includes at least one external spline extending therefrom. The scroll-type fluid compressor includes a bushing having an axis of revolution and an orbiting fluid displacement member which is movable in cooperating relationship with the bushing. The bushing has an aperture adapted to receive the drive pin including at least one internal spline mating with the external spline of the drive pin. Clearances defined between the external spline and the internal spline allow displacement of the disk shaped rotor in relation to the bushing upon rotation of the drive shaft. This displacement allows the line contacts occurring between the orbiting scroll and the affixed scroll of the scroll-type fluid compressor to separate, thereby allowing the scroll-type fluid compressor to start up in an unloaded condition.
